Abstract
The utility model discloses a side ladder, especially to a foldable side ladder for a shunting locomotive, which comprises two ladder rods (1) arranged in parallel. A group of parallel ladder support(2) are arranged at an interval on the ladder rods (1) and perpendicular to the ladder rods (1). Two ladder support (2) are rotatably connected with one end of a connecting rod (4). The other end of the connecting rod (4) is connected with a connecting shaft (8) which is positioned in an elongated hole (5) on a ladder seat (3) in the vertical direction. A stop stage (6) is arranged on the externalside face of the ladder seat (3). The height of the stop stage (6) is in the middle position of the elongated hole (5). An installing hole (7) is equipped on the ladder seat (3). The side ladder is close to the corridor sidewall at normal time, does not occupy the corridor space, provides convenience for the conductor and driver and is easy to operate. A big side ladder is manufactured, which isconvenient to climb.
Description
Technical field
The utility model relates to a kind of side ladder, particularly a kind of collapsible shunting locomotive side ladder.
Background technology
Railway shunting locomotive side ladder all is not collapsible at present, be installed on the side in locomotive corridor, because the restriction on the locomotive space, the corridor is all very narrow, and side ladder place leans out to the corridor owing to the side ladder, make the corridor Effective width reduce about 30%, this moment the driver and conductor can only lean to one side by, simultaneously in order to save the space, the size of side ladder must minimize, cause personnel inconvenient to pedal, but also have the danger of meeting and discussing.
Summary of the invention
The purpose of this utility model provides and a kind ofly do not take the space, corridor at ordinary times, when using convenient to pedal, the desirable collapsible shunting locomotive side ladder of size, overcome the deficiencies in the prior art.
Collapsible shunting locomotive side ladder of the present utility model, it comprises two terraced bars 1 that be arranged in parallel, on terraced bar 1, be provided with at interval and and support 2 perpendicular to one group of terraced bar 1 parallel ladder, it is characterized in that: wherein two ladder supports 2 all are rotationally connected with an end of connecting rod 4, the other end of connecting rod 4 and adapter shaft 8 join, adapter shaft 8 is positioned at the slotted hole 5 of the above-below direction on the ladder seat 3, lateral surface at ladder seat 3 has retaining platform 6, the height of retaining platform 6 is in the middle part of slotted hole 5, is processed with mounting hole 7 on ladder seat 3.
Collapsible shunting locomotive side ladder of the present utility model, during installation, ladder seat 3 is bolted on the sidewall of corridor by 7 utilizations of the mounting hole on it, the side ladder can be carried on the whole at ordinary times, make connecting rod 4 rotations and adapter shaft 8 move to the bottom of slotted hole 5, connecting rod 4 is incorporated in same plane with the side ladder, makes the sidewall of side ladder near the corridor, simultaneously by keeping off platform 6 retainings by connecting rod 4; When using the side ladder, upwards mention the side ladder, laterally rotate simultaneously as needs, make connecting rod 4 be in horizontality, and become 90 ° with the side ladder, the side ladder leaves the corridor sidewall, this moment, connecting rod 4 was pressed against the top of retaining platform 6, and adapter shaft 8 is in the top of slotted hole 5 to be blocked, and can normally use the side ladder.Side ladder does not take the space, corridor near the corridor sidewall at ordinary times, for the driver and conductor by convenience is provided, processing ease during use also can be produced the side ladder of size more satisfactory (greatly), pedals terraced more convenient.
